As the roller and the conductive cloth are rolled, the excess soaking liquid in the conductive cloth can be squeezed out, thereby avoiding the waste of the soaking liquid.

[0025] 3. The present invention cooperates with the second screw rod, lifting block, U-shaped plate, straight block, first motor and second motor.

[0047] Working principle and use process of the present invention: Conductive cloth is a special fabric with good conductive properties. It is usually made of conductive materials combined with ordinary textiles. It is widely used in electronics, medical, aerospace and industrial fields. Conductive cloth usually has good flexibility and is suitable for making various shapes and sizes. It is suitable for flexible electronic products. It has good wear resistance and corrosion resistance and can maintain performance in harsh environments. The automatic soaking device for conductive cloth is a device specially designed to soak conductive cloth in a specific solution. It is often used in industrial production processes, especially in the processing, cleaning, dyeing and surface coating applications of conductive cloth. The device is equipped with a heating and temperature control system to ensure the stability of the liquid temperature. To ensure that the liquid remains uniform during the soaking process The flow is uniform and the temperature of the liquid is consistent. The automatic soaking device is usually equipped with a liquid circulation and heating system. The length of the conductive cloth is different, and the position of the clamping structure is fixed. The shorter conductive cloth may not be completely immersed in the soaking liquid, while the longer conductive cloth may be soaked unevenly in the clamping part, which will also cause uneven dyeing. The excess soaking liquid may interfere with the conductive property of the conductive cloth. The inability to squeeze out the soaking liquid will cause the drying time of the conductive cloth to be significantly prolonged. Therefore, an automatic soaking device and soaking method for conductive cloth are designed. A suitable soaking liquid is injected into the interior of the soaking box 1. The soaking plate 21 is located on the top of the soaking box 1 at this time. The conductive cloth is laid flat on the surface of the soaking plate 21, and the two clamping plates 24 are moved left and right to make the two clamping plates 2 The bottom surface of 4 is in contact with the surface of the conductive cloth, and then one end of the two positioning columns 25 is embedded into the corresponding positioning hole 23, and the two are threadedly connected. The stability of the conductive cloth can be enhanced by the two clamping plates 24. After the hydraulic cylinder 20 is started, the U-shaped frame 29 connected to its output shaft is driven to move downward, and the immersion plate 21 will also gradually descend to ensure that the conductive cloth and the immersion liquid are completely immersed. This structure avoids the conductive cloth from folding and winding in the immersion liquid, ensures that each part can evenly contact the immersion liquid, and can also reduce the formation of bubbles, which helps to improve the efficiency of immersion. Through the movement of the two clamping plates 24, the conductive cloth can be clamped according to its width to keep it stable. After the immersion is completed, as the immersion plate 21 moves upward Then, the two clamping plates 24 are gradually separated from the conductive cloth, and the soaked conductive cloth is placed on the surface of the extrusion frame 3, so that the surface of the roller 18 contacts the surface of the conductive cloth. After starting the first motor 10, the first screw 7 connected to its output shaft is driven to rotate, which also drives the fitting block 8 threadedly sleeved therewith to move left and right, and the roller 18 will also move left and right. As the roller 18 and the conductive cloth are rolled, the excess soaking liquid in the conductive cloth can be squeezed out, avoiding the waste of the soaking liquid. After the roller 18 squeezes the conductive cloth, the excess soaking liquid will flow to the inside of the guide box 6 through the multiple leak holes 5, and then flow along the guide groove 28 to the inside of the soaking box 1. After starting the second motor 19, the second screw 12 is driven to rotate synchronously.This drives the lifting block 13 threadedly sleeved therewith to move up and down. Under the connection of the U-shaped plate 14, the position height of the roller 18 can be adjusted, so that the position of the roller 18 can be adjusted according to the thickness of the conductive cloth, thereby increasing the application range of the soaking device.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
